Apaper-filled capacitor is charged to a potential difference of v0=2.5 v. the dielectric constant of paper is k=3.7 . the capacitor is then disconnected from the charging circuit and the paper filling is withdrawn, allowing air to fill the gap between the plates. find the new potential difference v1 of the capacitor. v1= v
while the capacitor is disconnected from the charging circuit, an unknown substance is inserted between the plates. the plates then attain a potential difference that is 0.55 times the original potential difference v0 (when paper filled the capacitor). what is this unknown substance's dielectric constant?

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
